I currently have an F-Type 158 with V8 9.8 for light wind sailing. I really enjoyed last season and increased my time on water.

However, I am thinking of buying a couple of fins to add to the standard Drake 64cm and extend the wind range of the board. My weight is 100Kg and I am looking for a fin to really work best in the lightest of winds (70 or bigger) , and another one for stronger winds (52-56cm).

My focus is not on racing performance (points high angles etc) just early planning and easy performane on a straight line.

Q1. What would you propose? I read that the R19 is soft and thus, the one for light wind choice, but would that be OK for someone who is not a pro?

Q2. What is the S or M initials next to the R# name of the fins?

Q3. What is the effect of fin rake on the sailing?

Q4. What are the characteristics of the supplied Drake 64cm (soft, stiff etc)? What is its equivalent on the Decoichet line?

Hi pa10
Q1. What would you propose? I read that the R19 is soft and thus, the one for light wind choice, but would that be OK for someone who is not a pro?

A: Any 70cm will improve ultra light wind performance. As the tail width of the F-Type 158 is over 73cm, it should be fine, even the most powerfull 70cm fins will work with your9.8m sail I.E. Deb R19, C3 Bravo etc.

Q2. What is the S or M initials next to the R# name of the fins?

A: The "S" stands for soft, the "M" stands for medium etc. Soft means its more responsive to pump as it more flexible. A "Stiff" fin cuts through chop better than a "Soft" fin and a medium is kind of a compromise.

Q3. What is the effect of fin rake on the sailing?

A: Forward rake increases the power and pointing ability of a fin and would normally be geared towards the lower-end. Less rake is geared more towards top-end and usually gives higher speeds.

Q4. What are the characteristics of the supplied Drake 64cm (soft, stiff etc)? What is its equivalent on the Decoichet line?

A: Not sure what Debs equivalent shape is to a 2005 Drake, but the R13 looks pretty similair. The Drake is pretty soft compaired to a custom, but this is down to materials. Like a 100% carbon mast Vs 40% mast, the custom fin will feel more alive/responsive.

If your looking for max range out of the F-Type 158, maybe a 54cm, 64cm (supplied with board) and a 70cm will do this (Or sell the 64cm and get a 60cm & a 70cm). If the Drake fins agree with you, it would be good to get Drake 54cm & 70cm fins so they all have the same charicter.
